ROTARY AIR coivrrnnsson.

Application filed February l9, 1927. Serial No. 169,485.

the invention will be fully understood from the following descriptionand claims, when the same are read in connection with the drawings,accompanying and forming part of this specification, in which Figure 1is a side elevation of the compressor constituting the preferredembodiment of my invention. 7

Figure 2 is a transverse section of the compressor taken on the planeindicated by the line 2-2 of Figur 1, looking toward the right. k

Figures is a view'showing 111 straight or fiat state, the blade of mynovel compressor,

and certain appurtenances of said blade.

Similar numerals of reference designate correspochng parts in all ottheviews of the drawing. 7 I

Among other elements, my improvement comprises a tubular shaft 1, cappedor otherwise closed at one end as designated by 2, and designed at itsopposite end to be appropriately connected with a blow. pipe or anyother device to which it is desirable to furnish air under pressure. Thesaid tubular element 1 is designed to be journaled in standards or anyother appropriate supports, not shown. v

The tubular shaft 1 is provided at 3 with an opening in its wall, and itwill also be understood from Figure 1 that the shaft 1 is equipped witha pulley 4 or is otherwise adapted to be connected with power means forthe rotation at a high rate'of speed of the air compressing means on theshaft.

In the preferred embodiment of my invention, the said air compressingmeans is made up of two spaced discs 5' having enterior hubs 6,appropriately fixed at 7 to the shaft 1, so that the shaft 1 and thediscs 5 will turn as one piece. The said air compressing means alsocomprises a curvilinear blade 8,

preferably of sheet steel. Normally the said blade'8 is flat asindicated in Figure 8,,

and it will be noted that the said blade 8 is apertured at 9, and isprovided with trans verse rods 10, three in number, at points adj acentto its ends and also at a point intermediate of the first named point.The rods 10 are connected by shackles lljtoithe blade 8 and are arrangedat right angles to the length of the said blade 8, and have threadedportions12 extended beyond the longitudinal edges of the said blade8. 4

Inassembling the parts of the air compressing means, the blade 8 isdisposed in curved state between the discs 5, and adjustment is thenmade so that the threaded ends 12 of the rods 10 are extended throughapertures in the discs 5 so as to receive securing nuts 13, and struts14, preferably of steel, are interposed between opposite portions of theblade Sand are connected to the said blade portions through the mediumof bolts 15, Figures 1 and 2. v

It will be apparent from the foregoing that when my novel compressorconstructed as described is rotated at a high rate of speed about thecenter of the shaft 1, air will be gathered and compressed by thecurvilinear blade 8, and will be forced through the shaft 1 for use inactuating a blow pipe or any other suitable device connected with theeduction portion of the said shaft 1.

It will be appreciated from the foregoing that my novel air compressoris simple and inexpensive in construction, and is free of delicate partssuch as'are likely to get out of order after a short period of use.

It will also be appreciated that when operated in the manner described,my novel air compressor may be depended upon to furnish an amplequantity of compressed air for the proper operation of one or more blowpipes.

I have entered into a detailed description. of the construction andrelative arrangement of the parts embraced in the present and preferredembodiment of my invention in order tov impart a full, clear and exactunderstanding of the said embodiment. 'I do not desire, however, to beunderstood as limiting myself to the specific construction and relativearrangement of parts disclosed, my invention being defined by myappended claims Within the scope of which modifications may be madewithout departure from my invention.

Having thus lescribed the invention, What I claim is 1. An aircompressor comprising a tubular shaft having a lateral induction openingand also having; an eduction portion, spaced discs surrounding saidshaft and fixed thereto and disposed at opposite sides of said lateralinduction opening, and a resilient curviliuez r spiral blade interposedbet c011 and carried by said disc and spirally arranged about thelateral induction opening in the shaft; the said d acs being; providedwith transverae apertures, and the said blade being equipped withtransverse rods connected thereto and having end portions eeeured in theapertures of the discs whereby the discs operate to retain the blade inspiral state between the discs against the inherent resiliency oi theblade.

An air compressor comprising a tubular shaft having a lateral inductionopening and also having an eduction portion, spaced discs surroundingsaid shaft and fixed thereto and disposed at opposite sides of saidinduction opening, a curvilinear spiral blade interposed between andcarried by said disc and star-ally arranged about the induction openingin the shaft; the said blade being inherez'itly resilient and possessedof the tendency to resume a flat state, and being secured to and betweenthe disc and held by the discs against said tendency.

8. A rotary air compressor comprising a tubular shatt having a lateralinduction opening and also adapted to have an eduction portion connectedwith devices to Which it is desired to supply air under pressure, discsfined to the shaft and surrounding the same at opposite sides of theinduction opening and having transverse apertures, a resilient spirallycurred blade interposed between the discs and surrouliding thei11duction aperture oi? the shaft, transverse rods connected to the saidblades and having threaded portions extending}; through the transverseapertures in the discs, nuts on the outer sides of the diecs and mountedon and ine the threaded port-ions of said l'OC s, and struts interposedbetween and connected to opposite portions of the blades at pointsbetween the discs.

In testimony whereof I ailix my signature.

HENRY STRONG.
